Backdoor Virus

I was attacked in the past by a virus and had to reformat my computer. Once everything was removed I began the time consuming task of reinstalling my purchased games.
When I got down to Tumblebugs 2 I was shocked to find out that there was a backdoor virus attached to the file. Before you ask, YES, this file was from the Big Fish server. Can anyone give me any insight into this matter. Of the twenty plus games that my wife and I have purchased over the past year this is my favorite. Each attempt to reinstall this game comes back with the same result. Deleted by my Virus scanner due to having a known malicious backdoor virus rated 4 on a scale of 0 -5 with 5 being the worst. Is there anyone out there who has this same problem? Please help!!!!!!!!!

Big Fish games do not have any viruses now, or ever.

You could alway contact Customer Support.

I've had a couple of games that my security software wouldn't let me download because it said the game had a trojan horse attached to it. I finally had to disable the software so I could download from BigFish. I haven't had a problem in a while, though.
